The gloss black pre-finished cabinet was a great match to the woofer and tweeter in this design-- the varying shades of black provide an interesting though somewhat subtle contrast. The only modifications to the stock cabinet were adding a hole for the port and making the driver cutouts on the baffle. Since the port I used was our 2-1/2" adjustable port, the cutout needed to be 3", which I cut in the back with a hole saw, 6" down from the top. For the front baffle, I cut the driver recesses with the Jasper Circle Jig. The woofers are spaced 11-1/2" center-to-center, and the tweeter is offset by 3/4". The woofers require a 7-1/8" recess and a 5-7/8" through-hole; the tweeters require a 4-1/8" recess and roughly a 3-1/8" through-hole. You may need to cut some small "ears" in the tweeter through-hole to allow room for the terminals.
